j'To all whom itmay concern:

Be it known that I, OVID MINER GOULD, of

the city of Montreal, Province of Quebec,

% made), have invented certain new and useful s a full, clear, a

declare that the followi nd e same.

exact description of th My invention relates particularly to U brakes for controlling the speed of package mlO carriers, and retards the speed as the carrier .Inoves in one direction' and allowing" it he opposite I J ngl mprehension, however, of my ,5. invention reference must be had to the 2.0- companying drawing in which my improved keis illustrated in elevation partly in sectionJ.

For full .1

.My improved'controller consists of a rotai'y. brake whichin itself constitutes no part L 'ofthis invention .but has a novel and essen tial. controlling device in connection therebrake consists o'f a chamber 2, unted. and containing a pair of '5 5 intermeshing gears or piston-wheels-l and" 1 5 'mounted rigidly upon a pair of shafts 6 "and 7 extending transversely through the. casin while a sprocket chain 8 connects a sproc'et wheel .9.mounted on shaft 6 to a sprocket wheelnot shown mounted upon the 's' 'aft of the device tobe controlled. A pipe. 10. leads from a port in the top of the casing "n'lidway between the centers of the piston wheels, to one end'oi the casing of my controllerproper (to be presently further al- :lu'ded tolwhile an oil cup 14 is connected tofthe uppermost point of this pipe, and a 1 second pipe 1:2 leads from the underside of if? the casing, lII'thB'SQJILB vertical plane-as the do point with'which the-first mentioned pi e ,connnunicates, to the opposite endof the casing ,of my controllerjf This controller proper, consists of a pair of angle chambers 15 and, 16 coupled together by a valve cas'ng ,g5 ljhavingga valve chamber 18 midway of its .Jength. ands-the opposite sides of said ChflJIF .ber beingl'formed with valve seats 19 and-'20.

-;A valve spindle. 1. is located movably in this valvecasing and projects from one angle chamber. through the casing to the other aii'gle chamber and hasgthe valve proper 22 carried rigidlythereon midway of its length and between the valveseats 19 and. 20. The

valve is localized'r elatively to the seats and the extent of its movement adjusted by a l s i ab y 0 I l v I: on of Letters Patent.

What Izclaim is as follows? V 1. The combination with a chamber having an external pipe circuit leading from one side'thereof to the opposite side and such chamber anl pipe circuit being adapted to contain a liquidya movable part located in such chamber and the movement whereof causes the liquid tofiow through the latter chamber and pipe circuit being adapted to contain a liquid, a movable partlocated in such chamber and the' movement whereof causes the liquid to flow according to the direction of movement of the said movable part, of a valve chamber included in the pipe circuit and having-a .valve seat, a valve in the chamber tor controlling the flow of said v liquid through the seat, and a member Within the chamber, for limiting the movement of the valve towards its seat for the purpose of allowing the'li uid to fiow in either direction and retarding its flow through the seat to a greater degree than in the opposite direction.

'3. The combination with a chamber having an external pipe circuit leading from one side thereof to the opposite side and such. chamber and pipe circuit being adapted to contain a liquid; a movable partloeatedin such chamber and the movement whereof causes the liquid to How through the latter 'andthe duct in either direction according to the direction of movement of the said movable par t, of a valve chamber included in the pipe circuit, and having apair of valve seats,

a valve in the chamber between the said:.

valve seats and adapted to be seated on 40 either one for controlling the flow of said liquid through theseat and means within the chamber for limiting the movement of the valve towards either seat for the purpose of allowing the liquid to flow in either direction and retarding its flow through one seat to a greater degree than through the other.

- 4. The combination with a chamberhaving a movable part, angle chambers 15 and 16, valve casing 17 connected at its opposite ends to the angle chambers and having a valve chamber 18, a duct leading from one side of said first mentioned chamber to one of we. angle chambers, a second duct leading from the opposite side of said first mentioned erase";

chamber to the other angle chamber, said chambers and ducts constituting a circuit adapted to contain a liquid and the movement of said movable part being adapted to cause the liquid to flow through said circuit, such valve chamber presenting pair of seats, a valve located between said arts and adapted to be seated on either one thereof, a valve spindle projecting longitudinally through the valve chamber and having said valve mounted rigidly thereon, a pair of screw-threaded spindles screwed into the angle chambers in line with and adapted to receive and support the opposite ends of the valve s indle, means whereby the screw threaded spindles are rotated, and, means for supporting the valve spindle in line with said screw threaded spindle said scrowthreaded spindles-being adapted to limit the movement of said valve spindle,

5. -.The combination with a chamber having a movable part,langle chambers 15 and 16, valve casing 17 connected at its opposite ends to the angle chambers and valve chamber 18, a dhct leading? from one side of said first mentioned chamber to one of the angle chambers, a second duet leading from the opposite side of said first mentioned chamber to the other angle chamber, said chambers and ducts constituting a bircuit adapted tocontain a'liquid and the movement of said movable part being adapted to cause the liquid to flow through said circuit,

having. a

such valve chamber -.prescnting a pair of seats, a valve located between said seats and adapted to be seated on either one thereof,

a valve spindle projecting longitudinally through the valve chamber and having said valve mounted rigidly thereon, a pair of screw threaded spindles screwed into the angle chambers in line with and adapted to receive and support the opposite ends of the valve s indle, means whereby the screwthreade spindles are rotated the adjacent ends of thejsaid screw-threaded spindles bo-- ing chambered and receiving and limiting the movement of said valve spindle.

In testimony whereof, I have signed my name to this specificatiomin the presence of two subscribing Witnesses.
